Abstract:
The CIMsteel Integration Standards (CIS/2) are the
product model and electronic data exchange format for
structural steel project information. CIS/2 is intended
to create a seamless and integrated flow of information
among all parties of the steel supply chain involved in
the construction of steel framed structures. The
Industry Foundation Classes (IFC) are the product model
developed by the International Alliance for
Interoperability to facilitate interoperability in the
building industry. The recent interest in Building
Information Modeling in the AEC community has shown
there is a need for a mapping between the CIS/2 and IFC
product models. While the CIS/2 and IFC product models
have different views of modeling structural steel, a
useful mapping between the two product models was
developed. The mapping will permit structural steel
models from CIS/2-aware design, analysis, detailing and
fabrication software packages to be imported into
IFC-aware software packages to do model coordination
between the structural steel and the other parts of the
building such as floors, walls, windows, doors, and HVAC
systems. The mapping has been implemented as a CIS/2 to
IFC file translator. IFC files generated from CIS/2 have
successfully been imported into many IFC-aware software
applications including several of the major CAD
applications used in the AEC industry.
